(Y or N) Are you an upperclassman (i.e., have you spent three or more years in college)? The following table summarizes the responses to the survey. For each entry, "Number of Instances rep- resents the number of respondents having the corresponding values for the attributes TikTok, Instagram, and Facebook TikTok Instagram Facebook Y ZZZZ Y Y N N Y Y N N Y Y Y Y N N N N Number of Instances Upperclassman Not Upperclassman 5 0 0 20 20 0 0 5 0 0 25 0 0 0 0 25 (a) Find the support and confidence for the rule if Instagram = N then class = Not Upperclassman. (b) Find the support and confidence for the rule if TikTok = N and Facebook = N then class = Upperclassman. (c) Using the 1-rule method discussed in class, find the relevant sets of classification rules for the target variable by testing each of the input attributes TikTok, Instagram, and Facebook. Which of these three sets of rules has the lowest misclassification rate? 1.
